Quantifying the Impact of Construction Waste Charging Scheme on Construction Waste Management in Hong Kong

Abstract

5A considerable amount of solid wastes is generated every year from construction and demolition (C&D) 6 activities in Hong Kong. The C&D waste can be classified into inert and non-inert wastes, in which the 7 inert waste is normally disposed of in public fills as reclamation materials, and the non-inert part is dumped 8 at landfills. Under the current waste generation trend, all landfills and public fills in Hong Kong would be recycling. The findings also revealed that 40% of the survey respondents believed that waste reduction is 17 less than 5% after CWDCS has been implemented. The interviewees expressed that some waste generation 18 were unavoidable despite a waste disposal charge has been imposed. In addition, 30% of survey respondents 19 agreed that the cost of CWDCS was not high enough to raise the awareness on waste management on 20 construction sites.

Stakeholders’ willingness to pay for enhanced construction waste management: A Hong Kong study

“…Nevertheless, even after the successful implementation of the CWDCS in 2006, CWM in Hong Kong remains "a gloomy situation" [29,40]. Little improvement has been witnessed since, and the social-economic environment for CWM in Hong Kong has changed.…”

Analysis of the construction waste management performance in Hong Kong: the public and private sectors compared using big data

“…Hong Kong Advisory Council on the Environment's (ACE's) (2007) documents highlighted the two sectors separately in terms of CWM measures. Poon et al (2013) explained further that public sector projects in Hong Kong have imposed more stringent contractual clauses to reduce waste generation and often provided financial incentives for waste reduction; while private sector projects emphasize time and cost efficiency. Under the Coase Invariant Theorem, as applied to construction management by Lai et al (2008), there should be no difference in the performance between contractors working for different types of clients.…”

Joint use of construction waste (CW) and sugarcane bagasse ash sand (SBAS) in concrete

“…In Spain, 70% of all waste is generated by the construction industry. In the United Kingdom, Australia, Japan, Italy, the Netherlands and Finland the generation of CW corresponds to 50%, 44%, 36%, 30%, 26% and 14%, respectively, of the total waste generated [3].…”
